Integrated Graphics performance question(s)

Hello everyone,

I’m posting on behalf of a friend. The question relates to GPU {under?}performance in Rhino.

PC shows GPU Memory @ 16.2 GB, but only 512 MB ‘dedicated’ - render device option OpenCL only:

Rhino 8 says ‘Total Memory: 1 GB’:

A simple box in raytracing makes the PC sweat.

Why is this and is it possible to tap into more of the available ‘in-house’ GPU power? Could it be related to specific driver update? PC graphics settings already adjusted for Rhino to go for ‘high performance using AMD’.

I want to help my friend get the most out of Rhino with their current system! This, of course, before defaulting into suggesting dedicated graphics. It feels as if the system still has plenty integrated graphics for basic raytracing.

Do you have any insight/suggestions? I thank you in advance for your attention/support :slight_smile:

Best,
RC

That looks like a very old driver version (2022?).

The long and short of it, is that iGPUs don’t have intrinsic power to unlock. They are meant for lightweight applications and office shuffling.

If the driver is this old, the GPU may even be Zen 3 iGPU. It’s only recently that either AMD (Strix) or Intel (Meteor Lake) really have anything that may be close reasonable in an iGPU to do raytrace.

Not only that, they have probably the entire CPU and iGPU saturating the cooling solution if it is a thin & light laptop. Even if that’s not the case, if there is only an iGPU in the first place, it’s probably a truely more economical piece of silicon with low TDP (~20 W).

@David53 thank you - I was hoping the driver update could help a bit but the details in your response signal what will most likely be the outcome.
